Application filed July 5, 1916. Serial No. 107,619.

To all whom it may concern:

Be it known that I, HERMAN Foosn, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in False Work for Concrete Construction, of which the following is a' provision of a false work of this character wherein the columns and beams within a building edifice can be formed from con-- cretewith despatch irrespective of the height and length of the column and beam or the width thereof.

Another object of the invention is the provision of a false work of this character wherein, the same is of novelconstruction so that it can be readily assembled and will render the column or beam smooth, the false work being readily knocked down or removed after the formation of the column or beam so that the false work can be used continuously with minimum labor and time in the assemblage and removal thereof.

A further object of the invention is the provision of .a false work of this character which is readily adjustable in length and width, adapting it for varying sizes of columns and beams for the. formation thereof.

A still further object of the invention is the provision of a false work of this character which is extremely simple in construction, thoroughly reliable and efficient in construction, strong, durable and inexpensive.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claims. v

In the accompanying drawings: Figure 1 is a fragmentary side elevation of a false work constructed in accordance with the invention, showing the column and beam forms; Fig. 2 is a fragmentary vertical sectional elevation thereof; Fig. 3 is a horizontal transverse sectional view; Fig. 4 is a view similar to Fig. 3, showing a slight modification of the invention; Fig. 5 is an enlargedsectional view on the line 55 of Fig. 1; Fig. 6 is a vertical transverse sectional view through a beamform showing the head clamp thereforof a slight modification; Fig. 7 is a fragmentary horizontal transverse sectional view showing in detail one of the brackets used in the false work.

Similar reference characters indicate corresponding parts throughout the several views of the drawing.

Referring to the drawing in detail, A designates generally a column form and B a portion of a beam form constituting the false work hereinafter fully described in detaiLr.

The column form comprises the series of upper and lower substantially L-shaped sections 10 and 11 respectively, each being of the required length and having formed on one longer edge thereof a flange 12 outturned at right angles thereto, the flange being coextensive for a portion of the length of the section for a purpose pres ently described. The upper series of sections 10 are arranged in overlapping relation to each other to form a casement and likewise the series of lower sections 11 are arranged in overlapping relation to coact with the sections 1 ofthe casement. The sections 10 when arranged in overlapped relation are telescoped within the lower sections 11 so that the form A can be lengthened or shortened according to the height of th column to be formed. In the bights at the corners of the L-shaped sections 10 and 11 are formed registering apertures 13 adapted to receive tie bolts 14 so as to lock the upper and lower sections 10v and 11 together after the same have been adjusted in accordance with the height of the beam to be formed, the bolts 14 being readily removable when it is desired t-o-adjust the form A, as will be apparent.

At intervals throughout the length of the sections 10 and 11 exteriorly thereof and mounted at the corners of the same are brackets 15 having, upstanding keeper pins 16 for enga ement in registering apertures or holes 17 ormed in the bars 18 of adjustable frames which are arranged about the form A as is clearly shown in Fig. 3 of the drawing, and these frames prevent the separation of the sections 10 and 11 of the form.

The form A when set up permits the pouring in of the concrete at the upper end thereof for the formation of the column andafter the concrete becomes set the sections 10 and 11 can be separated for the knocking down of the false work, as will be obvious.

In Fig. 4 of the drawing there is shown a slight modification of the column form wherein the sections 19, constituting the top and bottom series thereof and are constructed similarly to the sections 10 and 11, have detachably engaged therewith supplemental plates 20, each being formed at one longer edge with a lock head 21 which is adapted to I engage with the companion flange 12 as shown, so that the cross sectional area of the column can be varied, thereby assuringa greater range of adjustment of the sections The beam form B comprises .lower L- shaped sections 22 and upper sections 23, the L-shaped sections being arranged in overlapping relation and likewise the upper sections 23 overlap the sides of the said lower sections to form a trough like structure into which is poured the concrete for the formation of the beam. The upper sect-ions 23 are formed with outwardly and downwardly bent flanges 24 for the interlocking engagement of sections thereof adjacent each other,

the lower sections '22 of the beam form B next to the column form A each being formed with a downturned lip 26 which is adapted to lock with the upper end of the column form A, as is clearly shown in Fig. 1 of the drawings, toprevent the separation of the, column and beam forms.

It is of course to be understood that where a gap exists between the beam forms B at the point of the column form A there are employed cheek plates 27 and 28 respectively, which overlap each other and are fastened to the sections 22 and 23 of the beam form as at 29, the section 27 being formed with a flange 30 corresponding to the flange 24 for engagement therein.

In Fig. 6 there is shown a head clamp for supporting the beam form B at intervals between column forms and comprises a suitable support '31 having the hollow cross head 32 in which is slidably mounted a beam 33 having longitudinally slotted end portions 34 in which are adjustably connected at 35 comprising upper and lower series of substantially L-shaped sections assembled to provide easements telescoping one within the other, pins permanently secured to the said sections for engagement with adjustable bars for clamping said sections together, means for adjustably connecting the upper sections to the lower sections, and means for permitting adjustment of the first named sections.

2. A false work for concrete construction comprising upper and lower series of substantially L-shaped sections assembled to provide easements telescoping one within the other, means exteriorly of the sections for clamping the same together, means for adjustably connecting the upper sections to the lower sections, means for permitting adjustment of the first named sect-ions, said sections each being formed at one edge with a flange at right angles thereto, and extensible plates detaehably engaged with the flanges for varying the sizes of the easements.

3. A false work for concrete construction comprising upper and lower series of substantially L-shaped sections assembled to provide easements telescoping one within the other, means exteriorly of the sections for clamping the same together, means for adjustably connecting the upper sections to the lower sections, means for permitting adjustment of the first named means, said sections each being formed at one edge with a flange at right angles thereto, extensible plates detachably engaged with the flanges for varying the sizes of the easements, and a beam form provided with; downwardly turned flanges for engagement with theupper cascment and including a plurality'of extensible sections arranged in overlapping relation to each other.

In testimony whereof I afix my signature.

HERMAN FOUSE.
